The Anti-Spam SMTP Proxy (ASSP) Server project aims to create an open source platform independent SMTP Proxy server which implements whitelists, Bayesian, and virus filtering to help stop unsolicited commercial email (UCE). Anti-spam tools should be adaptive to new spam and customized for each site’s email patterns. This easy to use tool works with any mail transport and achieves these goals requiring no operator intervention after the initial setup phase.

Release Notes: This release fixes many small bugs and includes support for basic virus scanning using ClamAV's free antivirus databases.
Release Notes: 1.0.6 has cosmetic and documentation changes, but 1.0.5 had a critical bugfix in the underlying database functions. All users with version 0.2.0 or higher are strongly recommended to upgrade.
Release Notes: This release includes bugfixes for a CRLF / Qmail problem with replies to email spam / notspam / whitelist submissions, and a fix for a bug where it didn't properly clean up all headers. It also contains the updated documentation.
Release Notes: Cosmetic changes and usability improvements were made. This release celebrates the transition from Beta to Production/stable.
Release Notes: This release contains a number of bugfixes, specifically with regard to RunAsUser, chroot, move2num, and the Analyze admin page. It also uses less RAM (about half) to rebuild the Bayesian database (rebuildspamdb.pl). ASSP now recognizes the BDAT SMTP directive, a bug which allowed some spam delivered to ESMTP servers that support CHUNKING to pass through undetected. There are also minor enhancements to improve spam detection, specifically in the way mail is pre-processed.
